The bone mineral density(BMD) is influenced mainly by genetic factors, gender, age, drug, smoking, drinking, nutritional status, composition, physical activity. The major components of body composition, lean mass and fat mass, each of which is a potentially modifiable factor, may influence BMD more than total body weight alone. The muscle strength is also regarded as predictive factor to the BMD and bone fracture. The purpose of this research was to investigate the correlation between bone mineral status and body composition. The subjects consists of 3519 age of 20-69. Body compositions were measured using a Biospace-Inbody4.0. Body composition variables were age, height, weight, body mass index(BMI), waist-hip ratio(WHR), % body fat(%fat), fat mass(FM), fat free mass(FFM). BMD measurements were done by dual-energy X-ray absorptiometry(DEXA) using a QDR-4500 densitometer at the lumber spine(L1-L4). Experimental data were analysed through SPSS windows 11.0 PC+, and analysed by using multiple correlation, multiple regression and analysis of variance(ANOVA). The experimental results from this study are the following. BMD was positively correlated with height(r=0.275, p=0.000), weight(r=0.223, p=0.000), BMI(r=0.075, p=0.000) and FFM(r=0.325, p=0.000). However, was negatively correlated with age(r=-0.345, p=0.000), WHR(r=-0.186, p=0.000), %fat(r=-0.063, p=0.000). Stepwise linear regression analysis showed that height, weight, FFM, age and WHR were associated with BMD. BMD was higher in women with high FFM. BMD was lower in women with high WHR and %fat.
